| Abstract | ||
| Populus euphratica cuttings were collected from 16 natural populations in 11 provenances of Iran. These populations cover most of the geographic distribution of this species in Iran. 30 cuttings (3 cuttings from every mother tree), from each population location were planted in an experimental field in Karadj Research Station. Survival percentage, tree height, diameter (at 0.5 m up ground), biomass (leaf, stem and root dry weight) and main root length parameters were measured at the end of each growing season. Results of analysis of variance showed significant differences among provenances of P. euphratica for growth parameters of diameter, height, leaf number, root dry weight, main root length (P>0.01) and leaf dry weight and stem dry weight (P<0.05). Survival varied from 20% (Gherekhlar) to 92% (Kerman and Tafresh) among P. euphratica provenances at the end of growing season. Also the Duncan multiple range test showed different classifications for growth parameters among P. euphratica provenances. Four provenances of Ramhormoz, Gotvand, Tafresh and Hamidiyeh had an average diameter (2.62, 2.37, 2.26, 1.92 cm ), height (2.51, 2.76, 2.43, 2.32 m) and biomass (87.8, 107.8, 114.8, 95 gr) after two years. | ||
